Dell Latitude E6420 processor error lights

Jump to solution

Hello everyone, I bought a dell laptop from Ebay a few weeks ago as I really wanted one but during the first week I replaced the thermal compound as their was almost none left. When I put the computer back together I got a processor error code, I checked to make sure everything was in place and indeed it was but after a few restarts the computer actually booted to my os with no issues, the computer ran perfectly fine till I shut it down and attempted to power the system on again, the same error was occurring so when I pressed the power button to shut the computer down it restarted ad booted to the os just fine. It still functions fine as I'm typing on it right now but the problem still on occasion persists.

Any help would be appreciated as I need this laptop in good working order for image processing.

There are two possibilities:  the less probable is that the CPU is bad.  More likely it's the system board that's bad.  Did you get any kind of warranty on the system?

Unfortunately I did not, I bought the system for $100 before I went on vacation and decided to change the thermal paste while I was away as I do this with all my second hand computers.  I do believe that you are right on the system board being bad as I noted that it can never keep the time despite changing the CMOS battery.  One thing I did see is that the processor was bent slightly, I do not have pictures of the processor from the side but I attempted to carefully straighten the processor and seat it properly.

Thank you for your reply, ejn63!
